Custom Domains

Every function gets a default URL at https://{function-name}.clusterbase.dev. You can also add your own custom domains with automatic TLS via Let's Encrypt.

Add a Domain

ccp domains add example.com
# ✓ Domain example.com added to my-app
#
# DNS Add this A record in your DNS provider:
#
#   Type:  A
#   Name:  example.com
#   Value: 34.xx.xx.xx
#
# › TLS certificate will be issued automatically

After adding the A record in your DNS provider, Traefik will automatically provision a TLS certificate via Let's Encrypt.

List Domains

ccp domains list
# › Domains for my-app:
#   • example.com
#   • www.example.com

Remove a Domain

ccp domains remove example.com
# Remove domain example.com? (y/N): y
# ✓ Domain example.com removed

Domain Requirements

• Must include a TLD (e.g., example.com, not just example)
• No scheme (https://), path (/), port (:), or spaces
• Maximum 253 characters

How It Works

When you add a domain, the API:

1. Adds the domain to the function's domain list in PostgreSQL
2. Creates a Traefik router rule for the domain pointing to the serverless runtime
3. Traefik automatically provisions a Let's Encrypt TLS certificate
4. Requests to your domain are routed to the function's active production deployment
